Description
The Halo effect is a theory that describes how a single attribute of a person can affect how we perceive others. An example would be voice quality. If someone has a pleasant sounding voice, the person may be perceived to be more attractive by others based on this single attribute. The Halo effect is situational. If you perform a task at a high level, this may lead to others having expectations of you to repeat this level of performance in the future. Conversely, if you underperform on a task, others may expect similar levels of performance in areas unrelated to the task (Example: Your do not do well at school so you are perceived to be a low performer in another area of your life). In marketing, the Halo effect explains why customers are sometimes biased towards certain products, simply due to a prior favorable experience with other products made by the same manufacturer. In this science fair project, you will videotape three people. In the first video, each person will talk about himself/herself or an experience he or she had. During the taping, the participants will present themselves in a natural and favorable way. In the second video, the three participants will repeat the same speech but make adjustments to some aspect of themselves, such as voice quality, posture, or facial expression. Subjects will view the first video and rate the person?s level of "likability". After viewing the first video, they will view the second video and give a second assessment on the person?s level of likability. Will the two videos be rated differently? 

Instructions preview
Pre-experiment * Recruit three people who are willing to have themselves videotaped for the experiment (the three people will not be participating in the actual experiment, and they should not be known by any of the participants of the study). You may want to ask friends or family members. As each person will be videotaped twice, you will want to identify each person by a number or letter for tracking purposes during the experimental procedures (Example: Person A, Person B, and Person C. Similarly, their videos would be video A part 1 and part 2, video B part 1 .....
